I have three other girls as well, who are just next door to Feria (not with Turtle, of course!), so she will be going in with them if the baby is a boy. I am not worried about introductions because Feria has always been the "peace-maker" type, very sweet and never bothered by other piggies. Which is good because one of my girls is very dominant! I will do a proper introduction on neutral ground, of course, and clean the cage, etc, etc. I'm really hoping the baby is a girl, which is how it looks right now, because then they all can be together and Turtle can be the little Romeo with all his women!
I think he would be very happy about that.
